The Lost Vikings: 3 Open Source Clones Compared
The Lost Vikings/Blackthorne Tools doesn't reimplement either game — it's a public-domain library and set of command-line tools for extracting, viewing, and decompiling the original DOS data files, with several known rendering bugs in its viewers. LostVikings, by contrast, is an actual playable native Linux/Windows port built by decompiling the original executable, and can optionally add SNES/Genesis-exclusive console content if the player supplies their own console ROM images; both require the original game's DATA.DAT file.

Known limitations
- rendering: Many sprites are rendered incorrectly or not at all in the level viewer due to unclear sprite set selection and palette handling.
- rendering: Packed 32x32 object sprites are not drawn; the game's sprite set selection mechanism is not fully understood.
- rendering: Blackthorne levels often do not render correctly; parts of the map appear to be folded and secondary tile maps for backgrounds are not supported.
- rendering: Palette animations are decoded but not fully understood or supported.
